Go too far in some of test, maybe, attracting jeer (9)
I believe the answer is:
overshoot
'go too far' is the definition.
(to overshoot is to go past)
'some of test maybe attracting jeer' is the wordplay.
'some of test maybe' becomes 'overs' (overs in test cricket).
'attracting' is a charade indicator (letters next to each other).
'jeer' becomes 'hoot' (I've seen this in another clue).
'overs'+'hoot'='OVERSHOOT'
'in' acts as a link.
(Other definitions for overshoot that I've seen before include "Maybe miss the green" , "Go past the mark" , "Fly beyond" , "fail to stop where intended" , "Go beyond the mark" .)
